Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity, see
page307.
•Check engine coolant anticorrosion/antifreeze
concentration.
•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing temperatures
see page249.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or of the electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
For driving instructions with snow chains, see page198.
Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
